Changing the headlight bulb
Time needed: About 20 minutes
If you, too, want to make your life easier, remove the following bits:
When you look at the back of the headlight, you'll see a big plug coming out of a rubber boot:
Give that plug a nice hard yank and it'll disconnect. There's no trick to it; nothing to squeeze or anything to get the plug out. It's held in strictly by friction, but it does require a little bit of force.
Next, just pull back the rubber boot:
Grab the bulb housing (the black plastic ring); twist it and remove it. The bulb will come out along with the plastic housing; be careful not to drop it (not that it really matters to you if it breaks since, presumably, it's burned out anyway).
The Beemer looks a little creepy with no face, doesn't it? Very Halloweeny.
ANYWAY. Insert the new bulb into the back of the headlight -- remember not to touch the glass! Line up the metal tabs on the new bulb with the recesses in the bulb housing to ensure that the bulb sits flush against the housing.
Insert the black plastic bulb housing ring and twist it to lock the bulb in place.
Now it's just a matter of reinstalling everything that you removed. There really aren't any tricks or gotchas, though I would recommend turning on the bike and making sure the new bulb works prior to tightening everything back up.
